I am unable to load the Flex 1500 USB Drivers because windows 8.1 reports them as not being signed correctly. Any fix for this ?

    The drivers are signed. Windows is having the issue. We just had a problem like this with another user and he had to reinstall Windows 8.1 to resolve the issue.

    Hey Tim, well I figured it out. I had to turn off secure boot on the Tablet. Yup thats right a Toshiba Encore 8" tablet and it now works fine. It actually runs Powersdr with out any problems on the 1500. One plus for being USB. Most tablets come with windows bitlocker and secure boot enabled, it took me quite a while to figure out that was the issue. Not sure why it was an issue but the drivers wouldnt load, and in the dialog box for the driver windows reported that they werent signed correctly. Anyway all is well now and I have the ultimate portable set up !

    On another note the screen is a bit off due to the resolution on the Tablet. Since tablets are becoming more common with windows 8 maybe the programmers can make some adjustments so the screen displays properly. The 1024 x 768 trick for net books doesnt do it.

    Thanks guys

    The Encore 8 is great on F1500, better than a 5 year old dual core and so much lighter than the laptop.
